Hello,
I have Jane Bower Dec 10, 1795-May 10, 1883 as 2nd wife of John 1780-1848. She is buried White Deer Baptist Church cem., Allenwood, Union co.,PA, In 1870 she is living with John & Sarah Pfleegor.

Jane Bower parents are George & unknown(Thompson)BOWER.Her sibling is John,who married to Sarah Quinn.There is a Biog of the Bowers in Lycoming that names the Sypher connection.
